In a code, 'A @ B' means 'A is the mother of B', 'A # B' means 'A is the brother of B' and 'A $ B' means 'A is the daughter of B'. Based on the expression 'P @ Q # R $ S $ T', how is R related to T?
R is the granddaughter of T. R is the daughter of S, and S is the daughter of T. That is two generations down from T, and since R is female she is T's granddaughter.

Explanation
R $ S means R is the daughter of S, and S $ T means S is the daughter of T. So T is the parent of S, who is the parent of R, making T R's grandparent. R is female, so she is T's granddaughter. 'Daughter' is wrong because it skips the generation of S. The first part (P @ Q # R) only shows that P is the mother of R's brother Q and does not change this result.
